Abstract

【課題】生産性及び品質を向上させながら斜板支持台の耐焼付き性及び耐摩耗性を高める。 【解決手段】回転軸５と共に回転するシリンダブロック９に複数のピストン１０が周方向に配置され、回転軸５が回転することでピストン１０が斜板１２に沿って案内されて往復運動するとともに、斜板１２の凸部３２は斜板支持台２０の凹部２２に傾動可能に支持され、凹部２２の支持面２２ａの少なくとも一部の法線上に斜板支持台２０と一体的に形成された壁２ｅが配置されている斜板式ピストンポンプ・モータ１の製造方法であって、斜板支持台２０の凹部２２の支持面２２ａに対してレーザ光Ｌ１，Ｌ２を走査しながら照射して焼入れを行い、支持面２２ａに対するレーザ光Ｌ１，Ｌ２の入射角度α１，α２に応じてレーザ光Ｌ１，Ｌ２の出力を変化させる。
